Abstract

A binder for a marine coating composition comprising the reaction product of a polysiloxane unit A′ and at least one second monomer B′ that undergoes a polymerisation reaction with said polysiloxane unit A′ so as to form a copolymer of structure -[ABAB]- wherein the backbone of said copolymer comprises a plurality of hydrolysable ester functional groups that will hydrolyse in the presence of seawater.
